Arrow VS learn-gdscript

One way is to create your narrative in Arrow, then export and use it as a database for your runtime/interpreter. The official HTML-JS runtime is based on the same idea. Arrow uses this runtime to create playable exports (mainly for play-test and review). Yet it means you can use this runtime (with customization) to export text-adventures directly from the editor as well. Another way is to create multiple chapters, scenes, etc. and export them as assets for your game (e.g. each scene or branch as a dialog-tree for your RPG).

JSON is just a text file with some specific conventions to be easily readable by other programs. Though, I took a look at the Inky's JSON export, and it's kinda convoluted. In your case Arrow might be a better fit. You can also consult with your programmer, since he'll be the person implementing your dialogue in game.

I use Arrow for dialogue/scene planning.

For others who are curious, here is the Arrow GitHub repository.

Arrow v1.0.1 is released and now has the textual save preference I promised.

New release of Arrow (v1.0.1) is out.

When I see someone wanting to start out and knowing nothing at all I do not point them at the 20 games challenge. I first point them at something like this: GDquest GDscript for total beginners . It at least attempts to teach some absolute basics as well as abstracting/hiding away useless and confusing framework you really don't want to be occupied with when learning from zero. But it's also guilty of assuming knowledge in some areas. That is sadly unavoidable. It also teaches almost nothing about object oriented design. (Something that should be looked up if you're working in an engine that has this as it's central design philosophy)

You can use this to learn GDScript https://gdquest.github.io/learn-gdscript/

Do you have any experience with programming? If not, you may want to start here https://gdquest.github.io/learn-gdscript/

If you have never done basic fundamental programming you can begin with https://gdquest.github.io/learn-gdscript/ , while this still hasn't been updated to Godot 4.0, it is universal enough not to be a problem.
